Well GT I think I'm going to go for it and get two of the Staphylea trifolia. Then I have to figure out which other two plants to get to meet the four plant minimum. I was thinking of getting a physocarpus opulifolia but MOBOT suggests they are susceptible to fireblight. I always thought Ninebarks were fairly bulletproof. Anyone have experience with them? I already have a ton of pyracantha and a single photinia villosa, both of which have some susceptibility to fireblight so I don't want anything else that could bring in that disease.
